Connection setup

SendGrid connection requirements.

Check the account access and change-detection requirements for your environment. Your system administrator can help confirm permissions before the first sync.

Connection method
REST API (v3)
Account access
API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
How changes are detected
The Stacksync guide does not specify the change-detection mechanism. Confirm it for the selected objects.

Setup guides and technical references

Integration design

Match records and fields for your SendGrid integration.

Define whether the goal is reporting communication activity, resolving customer context, or executing a new message/call action. The last option needs its own confirmed write method and business authorization.

Use your account’s actual field names when applying these matching and dependency checks.

Explore record matching and field-mapping checks
SendGridSource record IDKeep the account and record type
Record matchingSource ID ↔ destination IDLink the same record across systems
Selected destinationDestination record IDPreserve its local key and rules
Conceptual identity model. Keep source and destination IDs linked so an update reaches the right record. Confirm the supported sync direction separately.
Match the same record in both systems
Specify the grain of Email Activity versus Contacts or Lists. Keep the event or activity identity distinct from the person identifier so repeated events do not collapse into one contact row.
Load related records in the right order
Confirm Email Activity subscription and retention requirements before choosing a historical reporting window. Use a separate method for updates into SendGrid.

Mapping checks by record type

Contacts

Read: Supported. Write: Not available (read-only connector).

Identity
Use a stable person/contact ID and an explicit cross-system lookup. Email can change and can be shared, so treat it as a matching clue rather than a universal key.
Fields to consider
Source person ID · Display name · Email address · Organization reference · Consent state
Related records to resolve first
Resolve the organization relationship and any owner or consent references required by the destination.
Test before going live
Test an email change, two records sharing an email, and a person associated with multiple organizations.

Download the field-mapping workbook (CSV) to capture the actual API fields, matching keys, owners, and test results. Use it as you build with your team or a Stacksync engineer.

Setup and validation

Validate the SendGrid integration in four steps.

The reporting dataset retains distinct activity and participant identities. No delivery retry accidentally sends another message or places another call.

View the four setup tests and expected results

  1. Verify SendGrid credentials and resource scope

    Use the documented setup with the intended account, region or workspace, and resource scope. Record the credential owner and renewal procedure, then demonstrate access to one selected object.

    Expected result: The selected resource is accessible through the approved credential, with the renewal and revocation procedure assigned to an owner.

  2. Compare the same email activity window

    Select a supported resource and a period inside its available history, then compare the source records with the extracted dataset.

    Expected result: The destination preserves the required event/person distinction and the requested history is actually available.

  3. Compare source and destination data

    For SendGrid, compare the same source and destination scope, period, and filters. Test a later source correction and document how the destination reconciles it. Do not rely on return writes through this read-only connector.

    Expected result: The destination is traceable to the selected source dataset; changes in the destination are not mistaken for an application write-back.

  4. Test recovery and name the support owner

    Interrupt a non-production transfer, restore the connection, and reconcile the selected SendGrid records. When using Stacksync’s Retry to sync action, check the latest source value: the retry re-reads current source state rather than replaying an immutable historical event.

    Expected result: The records have the expected current values, repeated delivery creates no duplicate business record, and your team knows who handles unresolved errors.

Use the production-readiness checklist to record test results, assign support owners, and agree on when to go live.

Troubleshooting

Troubleshoot your SendGrid integration.

Diagnose record matching, delayed changes, and rejected operations
Older activity is missing while recent data is present
Check the Email Activity subscription and retention window before retrying extraction. The documented Stacksync connector does not write changes back to SendGrid.
The first load looks correct but later results differ
The Stacksync guide does not specify the change-detection mechanism. Confirm it for the selected objects. Measure the original source change, its capture, and the destination observation separately. Confirm whether the affected object is incremental, historical-only, or subject to a special refresh cycle.
One operation succeeds while another is rejected
The SendGrid connector cannot receive write-back. For outbound failures, compare the selected resource permissions and destination validation rules. Use a separate verified method for application actions.

Review retry, replay, and recovery behavior before repeating an operation that may already have succeeded.

FAQ

SendGrid connector FAQ

How should I plan an integration with SendGrid?

Define outbound email reporting scope and keep contact or sending operations outside this read-only route. This connector is read-only; choose a supported destination for its data. Start with one workflow, agree on which fields each system owns, then test initial data, later changes, and recovery before expanding.

Can the SendGrid connector write changes back?

No. The Stacksync connector is read-only for SendGrid. Use a supported writable destination for its data and a separate supported integration for changes in SendGrid.

Which identifiers should I preserve for SendGrid data?

Specify the grain of Email Activity versus Contacts or Lists. Keep the event or activity identity distinct from the person identifier so repeated events do not collapse into one contact row.

Which related records should I load first for SendGrid?

Confirm Email Activity subscription and retention requirements before choosing a historical reporting window. Use a separate method for updates into SendGrid.

What should I check if SendGrid data is missing or delayed?

Check the Email Activity subscription and retention window before retrying extraction. The documented Stacksync connector does not write changes back to SendGrid.

What should I include when estimating SendGrid integration costs?

Estimate the number of Contacts records, the history to load, ongoing changes, and required environments. Include API access, the integration service, destination storage or processing, and the work to maintain mappings and recover from errors. Review current provider pricing against that workload, including any account or API upgrades.

AI assistant

Set up SendGrid from Claude or ChatGPT

Connect the Stacksync MCP server to your AI assistant, then ask for the sync in plain language. You only sign in; there is no code to write and no API key to paste.

1. Add the Stacksync MCP server

Server URL

https://mcp.stacksync.com/mcp

In Claude

  1. Open Customize → Connectors, select + Add, then Add custom connector.
  2. Name it Stacksync and enter https://mcp.stacksync.com/mcp.
  3. Select Connect, sign in to Stacksync and choose your workspace.

In ChatGPT

  1. Open Settings → Apps → Advanced settings and turn on Developer mode.
  2. Select Create app, name it Stacksync, enter https://mcp.stacksync.com/mcp and choose OAuth.
  3. Sign in to Stacksync, then enable Stacksync from the tools menu in a chat.
Set up Codex or Claude Code

Codex

codex mcp add stacksync --url https://mcp.stacksync.com/mcp
codex mcp login stacksync

Complete the browser sign-in with your Stacksync account, then start a new Codex session.

Claude Code

claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp

Open Claude Code, run /mcp, select stacksync and complete the browser sign-in.

Then ask: “List my Stacksync workspaces.” Sign-in connects your assistant; it does not create a sync yet.

Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI and other assistants: setup steps in the docs.

2. Ask your assistant

Create a sync between my SendGrid and another app or database.

Also from the same chat

You can also ask for workflows and AI agents (Genies) that use SendGrid. The assistant checks what each app supports, for example:

  • “Build a workflow that messages our team in Slack when a SendGrid record changes.”
  • “Create a Genie that answers questions about our SendGrid data in Slack.”

What happens next

  • Signs you in with your Stacksync login (OAuth). No API key is pasted into the chat.
  • Gives you a secure sign-in link for each app it connects; you open it and sign in to that app.
  • Builds the sync with your permissions in Stacksync, nothing more. Turn on Ask before every change in the MCP settings to approve each change first.

New to Stacksync? Create an account first, then sign in from your assistant.
